We heard from a client that AutoFill in Safari suddenly stopped entering her name and address in Web forms when she chose Edit > AutoFill Form or pressed Command-Shift-A, forcing her to enter her contact information manually, like an animal. (And yes, the “Using information from my contacts” checkbox was selected in Safari’s AutoFill preferences.) Although we have no idea what caused the problem, the solution turned out to be simple. She went into Contacts, found her personal contact card, and chose Card > Make This My Card. Give this a try if you’re having trouble with AutoFill or haven’t yet started using it in Safari.
